United States Patent C STORM WINDOWS Charles P. Pengelly, Merchantville, N. J., assignor to Air Master Corporation, Philadelphia, Pa., a corporation of Pennsylvania Application July 15, 1954, Serial No. 443,605

Claims. (Cl. 20-55) This invention relates to storm windows and more particularly concerns storm windows of the self-storing type which has sliding sashes removable from the inside for cleaning or repairing.

Self-storing storm windows are usually provided with three sliding sashes carried within a permanently mounted frame. Two of the sashes are glazed and, during the winter, these are positioned one at the top and one at the bottom of the frame to serve as a storm window. The remaining sash is screened and during the summer the bottom glazed sash is raised to the top of the frame and the screened sash is used to cover the bottom opening of the window.

The United States patent to Spector et al. No. 2,595,016 discloses a self-storing storm window of the general type to which my invention pertains. But it is to be distinctly pointed out that my invention can be used with any type storm Window with a main frame containing guideways adapted to receive the herein described slidable sashes. As will hereinafter appear, my invention eliminates the necessity for passageways in the guideways that permit removal of the sashes in the patent to Spector et al., and also eliminates the stop fins that prevent lateral movement of the sash. Keeper holes in the guideways to lock the sashes in raised or lowered position are likewise unnecessary.

The primary object of the invention is to provide a sash manipulating and locking means which will permit the sashes to be quickly and easily inserted into and removed individually from the main frame of the window without disturbing the other sashes and by which the sashes are slidable up and down in the frame, are locked at any desired position, and are prevented from lateral movement and rattling in the frame.

One advantage of the invention is that it permits the use of continuous channels and obviates the need for entrance passageways for the sashes. The portions of the channel surrounding such entrance passageways in the Spector patent, supra, were subject to blows when inserting and removing the sashes and tended to bend out of line making insertion and removal of the sashes difiicult.

Another advantage of this invention is that the parts thereof are of simple, durable construction, and may be produced efilciently on a mass production basis of aluminum or any other suitable material.

Further features and objects of the invention, as well as the details of a typical embodiment thereof, will be understood from the detailed description to follow, throughout which reference is made to the accompanying drawings wherein:

As herein exemplified, my improved window structure comprises a main frame 21 having a lintel 22 and a sill 23 joined by two vertical, spaced jambs 24, 25. The structural elements forming window frame 21, including the lintel 22, the sill 23 and the jambs 24, 25 are preferably made of extruded metallic sections. The window frame 21 is inserted in a window opening of a building in a conventional manner and secured therein by bolts or other fastening means which pass through the holes 26.

As shown more clearly in Fig. 2, the jambs 24 and 25 are provided with three stepped channel shaped grooves or guideways 27, 28 and 29 defined by the channel separating fins or flanges 30, 31, 32 and 33. The fins 33 are farthest from the inside of the building and the lateral distance between fins 33 is less than that between fins 32, with fins 31 and fins 3t) spaced apart at progressively greater distances.

The lintel 22 is provided with stepped channels 34, 35 and 36, see Fig. 3, which correspond with the channel shaped guideways 27, 28 and 29 of the jambs 24, 25. These lintel channels 34, 35 and 36 are defined by fins 37, 38, 39 and 40. When the jambs 24, 25 and the lintel 22 are assembled with a mitered joint as shown in Fig. 1, the jamb guideways coincide with the lintel channels to provide continuous stepped channels or grooves around the inside of three sides of the window frame 21.

The sill 23 is fitted to the jambs 24, 25 with a mitered joint and is provided with upstanding fins 41, 42, 43 and 44. Fin 41 lies in the same plane as lintel fin 40 and jamb fins 33'.

As shown in Figs. 8 to 12, a slide sash 45 comprises two vertical spaced members 46, 47 the upper and lower ends of which are joined by horizontal members or rails 48 and 49 respectively. A U-shaped channel 50 runs along the upper edge of horizontal member 48, and a. similar channel 51 appears along the lower edge of member 49 while channels 52 and 53 run along the outer edges of vertical members 46 and 47.

A glass-receiving channel 54 extends along the inner edge of the members 46, 47, 48 and 49. A pane of glass 55-is received in the channel 54 and sealed therein by means of an extruded rubber seal 56. The fastening means for the corners of the sash 45 comprise right angle brackets 57 having legs 58, 59 which are placed within.

the outer channels 50, 51, 52 and 53 of the sash 45. De-

pressions 60 are provided in the brackets 57 and the draw nels 50, 51, 52 and 53 are pressed at points 61 into depressions 6% to assemble the sash. Laterally extending bosses or lugs 62 from the two brackets 57 at the top of the sash are adapted to be received in the jamb channels in which the sashes are slidably mounted. I

At the bottom of member 49 is provided a recess 63 formed by the downwardly extending flanges 64 and 65. Arranged within this recess 63 at each end of member 49 is the slide bolt mechanism of Fig. 7. This mechanism comprises a block 66 which is press fitted to "flange 65 at point 67. Block 66 is provided with a shank68 and a split shaft 69. The shank 68 fits within the end of a cylinder 70 to which shank 68' is affixed by a pin 71 which is inserted into a hole 72 of shank 68-and into a hole 73 of cylinder 70. Split shaft 69- anchors'one end of a spiral spring 74. The other end of spiral spring 74 is held by a split shaft 75 of a slide bolt 76. 'Sh'aft'7-5 is joined to a cam '77 by a shaft 78. A narrow slot is formed in the end of cylinder 70 and leads'into awider slot 81. In assembly, a grasp projection or handle 79 of bolt 76 slides through the slot 80 into slot 81 wherelthe torsional action of spring 74 turns the handle '79 toward a face 82 of slot 81 and the expansion force of spring 74 urges handle 79 into abutment wit-ha shoulder 83 of'slot 81. Shoulders 83 and 84 limit the sliding movement of the handle 79 in the slot 81.

A sash 85 .is provided for gnideways 28 and is identical in construction to the sash 45 except that ithas laterally larger dimensions since guideways 28 are spaced farther apart than guideways 29. A sash 86 is provided-for guideways 27 and is similar in construction to sash'45 except that it is wider in order to fit within the wider spaced guideways 27 and carries a screen 87 in place of a window pane.

The sash 45 is inserted into the window -frame 21- by holding the sash in a position away from the horizontal and placing the bosses 62 in the guideways 29. The lower member 49 of sash 4.5 is then broughtinto alignment with guideways 29, the slide bolts 76 being ret acted to permit such alignment. The bolts 76 are released and cam 77 is permitted to enter guideways 29 with cams 77 in their sliding position. The sash 45 is then raised or lowered to the position desired, and the handle 79 allowed to rotate so that cam 77 assumes its wedging position to lock sash 45 in place. Fig. 6 illustrates the sliding position and Fig. 5 shows the wed-ging position of cam 77.

It is to be understood that the features of the self-storing storm :sash herewith shown and described may be incorporated in other windows and that the invention is not limited to the preferred embodiment disclosed. Various changes may be made in the shape, size and arrangement of parts. For example, equivalent elements may be-substituted for those illustrated and described'herein, parts may be reversed, and .certain :features of the invention,

especially the device of Fig. 7, may be utilized "independently of the use :of other features, all without departing from the spirit of the invention or the scope of the subjoined claims.
